2 Claims.

This invention comprises novel and useful improvements in a syringe, and more specifically pertains to an improvement upon the invention set forth in the prior patent of J. W. Brunett, Patent No. 1,751,507 of March 25, 1930.

This invention is primarily concerned with providing an improved and highly efficient construction of the syringe needle which has been advantageously adapted for injecting douche fluid into the vagina and draining the same therefrom, although it is not to be so limited and may be employed as a surgical instrument to facilitate the cleansing of any bodily cavity.

The principal purpose of this invention therefore resides in providing a syringe for injecting a spray into a bodily cavity, and for withdrawing the same.

A further object of the invention is to provide a syringe in accordance with the precedin object which has an improved construction of liquid sealing for temporarily sealing and enclosing a bodily cavity during treatment by the spray.

Another important purpose of the invention consists in providing an instrument in accordance with the above-mentioned objects wherein concentric passages are provided in the body of the instrument for introducing and Withdrawing a medicament or spray from a bodily cavity.

A further important purpose of the invention to be specifically enumerated herein, resides in the provision of an improved syringe which shall be of compact and simple construction, with a spray nozzle readily removable for purposes of cleansing or purposes for replacement; and wherein the syringe may be equally useful for manual operation or from a power source for supplying and withdrawing the spray as desired.

These, together with various ancillary objects of the invention which will later become apparent as the fOllOWiIlg description proceeds, are attained by this device, preferred embodiments of which have been illustrated by way of example only in the annexed drawings, wherein:

Figure 1 is an elevational view showing the syringe according to a first embodiment of the invention;

Figure 2 is an enlarged elevational View of the syringe nozzle tube removed therefrom;

Figure 3 is a horizontal sectional view taken substantially upon the plane of the section line 33 in Figure 2 and showing the concentric construction of the nozzle;

Figure 4 is a vertical sectional view through the form of the invention shown in Figure 1, showing the interior construction and passage arrangement thereof, this view being taken substantially upon the plane of the section line 4-4 of Figure 3;

Figure 5 is a horizontal sectional detail view taken substantially upon the plane of the section line 5-5 of Figure 4;

Figure 6 is a horizontal sectional view taken substantially upon'theplane of the section line 6-6 of Figure 4 and showing further details of the passage construction of the device;

Figure '7 is a view similar to Figure 4 of a second modification of the invention;

Figure 8 is a fragmentary perspective detailed view of the base portion of the nozzle element of Figure 7;

Figure 9 is a horizontal sectional view taken substantially upon the plane of the section line 9-9 of Figure 7;

Figure 10 is a fragmentary elevational view, parts being shown in section, in an exploded position of a further modification of the invention; and,

Figure 11 is a horizontal sectional view taken substantially upon the plane of the section line II-ll of Figure 10.

Referring now more particularly to the ac companying drawings wherein like numerals indicate similar parts throughout the various views, reference is made first to the embodiment of Figures 1-6, wherein I0 designates generally a complete syringe assembly which as shown consists of a base member l2 upon which is detachably secured a nozzle member I4. I

As shown thus in Figure 4, the base member l2 comprises a body portion whose upper end termi-' mates in an outwardly flaring, dished, cup-shaped shield or rim l6, which is adapted to conform generally to the contour of the human body about the vagina or another body cavity for water tight sealin engagement therewith, this shield portion being provided at its lower end with an annular reservoir or liquid collecting chamber [8. At its inner or lower end, this chamber or reservoir I8 is provided with a shoulder portion 20 which is screw threaded as at 22 internally thereof. Ex-

tending outwardly of the body portion I2 from the shoulder portion 20 thereof, is an axially disposed concentric bore 24 whose bottom wall 26 tapers downwardly and discharges into a longitudinally extending fluid discharge passage 28 which may be detachably connected to a flexible conduit or the like 30.

The body portion I2 is preferably provided axially thereof with a concentric integral upwardly extending sleeve like portion 32 whose upper end 34 terminates at considerable distance above the upper extremity of the shield l6. As will be seen by reference to Figures 4 and 6, the V bore 24 and sleeve 32 define an annular sleeve like passageway 36 constituting a fluid discharge passage.

As will readily be seen by reference to Figures 4 and 6, the discharge passage 28 is eccentric with respect to the axis of the body 12, and with respect to the of the box-e24, to give adequate area to the inlet'and outlet passages-of the body. The tubular sleeve 32 at its lower end communicates with a transversely disposed fluid inlet passage 38 with which may be detachably;

connected a flexible fluid conduit 40.

It should be here noted that if desired, a. conxventional type of collapsible rubber bulb, may be employed in place of the conduit 40; or as de'- sired; or if preferred manually or automatically operated pump means may be provided for supplying and withdrawing fluid through the; pase est'aand asdesiredt r A detachable nozzle member is received in the. threaded, bore 2 2, f the, bodymemben. suc zzle ein d et det ,HQW Q, t o be distinctly understood that, uarious types and constnuctions; of nozzles maybe employed depending upon the nature of the c1eansing opera.--

tion tofbe performed. A l W V Y Preferably a, nozzle li isprovided with. an elongated body which may beof hollow tubular construction, and prqvided with a bulb head or, upper end portion 42. The'nozzle adjacent its head, or end is provided withaplurality of ap propriately positioned orifices 44 for emitting: luid in the form of a spray in treating a patient.

At its lower end, the nozzleis provided withan outwardly flaring portion'lfi whichis, externally threaded at; its lower extremity as at 4-2 for cooperative engagement and attachment .withthe or by pump means through the flexible conduit 30. 7

It should be distinctly noted that the use of this instrument permits a continuous flow of fluid through the inlet nozzle, and a return or discharge of the spent or used fluid without inz\fiixedif/Q its upper end, a transverse inlet con- V tending Sleeve member 18 extending abovethe duit 64 and a longitudinally extending and depending outlet conduit 66' is provided, thebody having; at 0,61'lt13113'cd-1S130fifidg tubular axiallyexupper .ta-p' sideof, the, shield J52. As so farole,- scribed this construction is. identical with that of the; preceding embodiment; The nozzle 68 hr ad b re Z2v forv emovabl'y-. attaclune he-- nozzle and the body member l2.

which may be easily disassembled for thorough sterilization of its components, may be readily provided with interchangeable nozzles to meet various situations, and which is so constructed as to efiectively enable a patient to satisfactorily and conveniently perform various treatments upon his or her own person.

A still further modification of the invention, having quicker and easier fastening means is shown in Figures and 11. This modification is substantially identical with that disclosed in Figures 7-9, diflering therefrom by substituting another type of threaded connection. Thus, a base 90 is provided with the concave shield 92 from which axially protrudes the tubular sleeve 94, engageable in the detachable nozzle 96 having axially extending notched terminal fingers 98. Within the bore of the nozzle 96 are provided a plurality of segmented or broken threads I00, cam

surfaces or the like for locking engagement with corresponding members I02.

The construction and operation of this form of the invention is otherwise the same as of the embodiment of Figures 7-9.

Since various modifications will readily occur to those skilled at the art after a consideration of the foregoing specification and attached drawings, it is not intended to limit the invention to the exact arrangement shown and described, but all suitable modifications may be resorted to falling within the scope of the invention claimed.
